FACTORS AFFECTING SPOILAGE MICROFLORA SUCCESSION ON LAMB CARCASSES ATREFRIGERATION TEMPERATURES

Three bacterial groups were detected during the shelf-life of lamb car casses stored at refrigeration temperatures: coryneforms (mostly Broch othrix thermosphacta), Gram-positive cocci (staphylococci) and Gram-ne gative bacilli (Pseudomonas spp. and Moraxella spp.). Influence of cat egorical variables such as sampling day, sampling area and sampling me thod on their recovery was analysed by a chi-square test of independen ce and loglinear analysis. Hierarchical loglinear modelling proved to be very useful as several three-way interactions of factors were obser ved.
